DYEING APPARATUS.

Specification of Letters Patent.

Application filed March 9, 1910.

Patented June 27, 1911.

Serial No. 548,273.

To all whom it may concern:

Be it known that I, THOMAS I-InRvnY DANIELS, a British subject, residing at Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Dyeing Apparatus, of which the following is a specification.

This invention relates to improvements in rotary dyeing machines of the type well known as Klauder-Weldon machines with the object of rendering such machines applicable to the dyeing of raw or loose wool, cotton or other loose material.

In the Klauder-Weldon type of machine as now constructed a rotating drum divided into compartments by partitions, is mounted in a trough shaped vessel containing the dye liquor in which the drum is partly immersed. For dyeing loose or raw wool experience shows that this construction is de-' fective as the tendency of the wool when packed in the drum and subjected to a constant rolling is to become more or less felted and further it is applicable only for use with a very limited range of dyestuffs.

This invention consists essentially in constructing the rotary drum with a hollow perforated structure in each of the compartments around which the loose wool (or other loose material) is packed.

The invention will be fully described with reference to the accompanying drawings forming part of the specification.

Figure 1 is a transverse sectional elevation. Fig. 2 is an enlarged detail end elevation of one of the perforated cages or boxes. Fig. 3 is a plan of part of same.

The rotary drum A is constructed with a number of compartments a separated by partitions a in the usual way. In each of the compartments (1 a hollow perforated structure B is fitted. The structure B is in the form of a drum, cage or box and is preferably removable being held in position by a hinged clamp or cap Z) being secured by a pivoted bolt 7; and wing nut 6 If desired the box or cage may .be a permanent fixture. The hinged clamp b is secured to the end of the drum by a plate 6 The hollow perforated structureB may be made of sheet metal such as copper or galvanized iron, or it may be made of copper or galvannlzed wire, or it may be built up of wood laths or perforated boards or other material suitable to resist the action of the dye liquors. The structures B may be of cylindrical, rectangular or other convenient shape.

The structures B, around which the wool or fiber to be dyed is packed in the compartments a of the drum A constitute open spaces in the interior of the mass of fiber, which fill with dye liquor at each rotation of the drum A, and act as reservoirs for the dye liquor when the drum emerges therefrom, from which the liquor is slowly discharged back through the loose wool or fiber as the drum continues to rotate. This quantity of liquor retains the heat, and keeps the wool or fiber longer in contact with the dye liquor and the wool or fiber is prevented from becoming rat-tailed, through the re- ?itkfiction by the cage of the movement of the By this construction of dyeing apparatus the material to be dyed is longer in contact with the boiling dye liquors, is more evenly penetrated by the same, and its movement being restricted is kept in better condition for subsequent spinning.

In the accompanying drawings a vat or tank V of suitable structure is shown as supporting the drum A. This vat or tank forms no part of the present invention and may be of any approved type adapted for the purpose.

What I claim as my invention and desire to protect by Letters Patent is 1. In a dyeing apparatus, the combination of a drum divided into compartments, and a hollow perforated structure applied at the central portion of each of the compartments and around which the material to be dyed is packed.

2. In a dyeing apparatus for dyeing loose wool or fiber, a rotatable drum divided into compartments, a hollow perforated structure removably fitted in each of the compartments, and means secured to portions of the drum to retain the perforated structures in position therein.

3. In a dyeing apparatus, the combination of a rotatable drum divided into compartments, a hollow perforated structure remy hand in presence of two subscribing witmovably fitted in the centrlal portion of each nesses. of the compartments, anc clamps fixed to the sides of the drum to engage the hollow THOMAS HERVEY DANIELS 5 perforated structures and hold the latter in Witnesses:

fixed position in the drum. J. OWDEN OBRIEN, In testimony whereof I have hereunto set HARRY BARNFATHER.
